Changed from Image to Directory, what does docker memory size mean now?

[Andiroo2]

On the Unraid dashboard, my Docker gauge is showing 90%.  When I used a docker image, this meant that I had filled the image to 90% of the specified size.

 

What does this number mean for the directory-formatted Docker data?
